What version of Firefox are you running, and what Add-Ons do you have installed? n=1 anecdote: I'm on a 2016-vintage Macbook Pro, Firefox 81.0, 64-bit, with >1100 tabs spread across 6 windows. I'm pushing the limits trying to establish whether to commit to Firefox or Chrome, and so far while lots of people seem to like Chrome, I'm strongly preferring Firefox. I could not get Chrome to stay stable enough with that much resource utilization, and the most important part I've learned is that Firefox's profiles storage formats are open enough that I've been able to recover from some pretty bad kernel panics (due to the graphics card switching on my laptop; disabling that fixed the panics). Probably next Macbook Pro refresh cycle from Apple I'll upgrade to the latest they introduce, but Firefox-as-daily-driver has been able to take a lot of abuse from me.
